From a social and political point of view, Lewis Hine was the most important and influential photographer of the 20th century. His photographs of child labor for the National Child Labor Committee, perfectly represented by the picture on the Committee's pamphlet which you see here, brought the human face of factory working conditions to the middle class magazine readers and voters who had the power to influence Congress. Without him the sort of reforms which were brought about in the first half of the century would likely have been postponed for at least a generation. A better spent life than Hine's can scarcely be imagined.
